Title: Preparation of honeycomb catalyst
Inventor: ONO TETSUTSUGU
IPC: B01J23/40
Filed: 1982-03-01
Abstract: PURPOSE:To enable the preparation of a catalyst in good efficiency by simple manipulation, by a method wherein water and, according to necessity, an acid and a slat are added to a catalyst composition obtained by supporting a catalytically active component by a refractory metal oxide to fix the same thereto and, after the obtained mixture is ground and dispersed, a honeycomb carrier is coated with the resulting homogenous mixture to be dried. CONSTITUTION:Refractory metal oxide (e.g., activated alumina) having a particulate or a granular form with a diameter of 1-5mm. or a columnar form with a diameter of 1-4mm. and a length of 2-10mm. and compression strength of 0.5- 6kg/grain is impregnated with a base metal compound (e.g., iron nitrate) and/or a noble metal compound (e.g., palladium nitrate) as catalytically active components to support the same and said catalytically active components are fixed by drying and baking.

Title: Commutator for rotary electric machine
Inventor: SAKUMA YASUJI
IPC: H01R39/04
Filed: 1980-03-13
Abstract: PURPOSE:To uniformalize the contact of an inward inclination surface of a V-shaped projection of a clamp ring holding a shrink ring of a commutator and an outward inclination surface of the shrink ring under an operation condition and hold the commutator positively by making an inward inclination angle of the V-shaped projection slightly smaller than an angle of inclination of the outward inclination surface of the shrink ring of the commutator opposing to the inward inclination surface. CONSTITUTION:V-shaped grooves 4, 5 are formed at both sides in the axial direction of a shrink ring of a commutator 1, and the V-shaped groove 4 at the riser section 19 side is connected to a V-shaped projection 8 made up to a spider 6. A clamp ring 10 with a V-shaped projection 11 is fitted to the V-shaped groove 4 at the anti-riser section side to clamp and hold the shrink ring of the commutator 1. In this case, an inward inclination angle beta2 of the V-shaped projection 11 of the clamp ring 10 is made smaller than an outward inclination angle alpha2 of the V-shaped groove 5 only by the difference DELTAtheta of the displacement of the V-shaped projections 11, 8 in case of operation. Thus, since the V-shaped groove 5 and the V-shaped projection 11 contact uniformly when operation, the shrink ring of the communtator 1 can be held positively even in case of high-speed operation, and the deformation of the shrink ring of the commutator 1 and the generation of accidents can be prevented.

Title: Optical inverter circuit
Inventor: TASHIRO YOSHIHARU
IPC: H03K19/14
Filed: 1991-01-31
Abstract: PURPOSE:To facilitate manufacture by connecting a first semiconductor laser element of a high threshold current and a second semiconductor laser element of a low threshold current in parallel, and driving them by a DC constant current source. CONSTITUTION:When the current of 50mA is supplied from the DC constant current source 5 to the first and the second semiconductor laser elements 2, 3, the current of 25mA flows in each of them. The laser element 3 emits light because its threshold current of oscillation is below 25mA, and an optical signal is outputted from a second optical transmission line 4. On the contrary to this, the laser element 2 does not reach oscillation because its threshold current is over 25mA. When the optical signal is made incident on the optical transmission line 1 in such a condition, the laser element 2 biased lower than the threshold current operates as a light amplifying element, and emits the optical signal from the optical transmission line 6.
